- BEVEL Fil-ed sept. 1, 1957 f@ @www torneys Patented Dec. 13, 1938UNITED STATES PATENT OFFICE 1 Claim.

The present invention relates to measuring tools, appliances, andinstruments, and has reference to a so-called adjustable bevel havingincorporated therein certain structural refinements and improvementscalculated to enable it to be more satisfactorily'employed to theadvantage of printers, carpenters, draftsmen, cabinet makers, and othersengaged as lay-cut men and satisfactorily usable to find any and allangles, whereby to especially adapt it to take any angle from a printerslay-out and transfer that angle to a saw trimmer table without movingthe table or gauge.

Briefly, the preferred concept is characterized by a pair of principalpivotally connected component parts one of which is in the nature of asheath and the other adapted to fold thereinto, the two parts havingassociated therewith a hand regulated stay link.

My primary aim is to generally improve upon bevel-squares and equivalentmeasuring instruments by providing a unique collapsible arrangement withthe features constructed to nest together in jack-knife fashion so as topromote compactness and convenience for a tool box and similar usage.

Other features and advantages will become more readily apparent from thedescription and drawing.

In the drawing:

Figure l is an elevational view of a bevel or tool constructed inaccordance with the principles of the present inventive conceptionshowing the same used as a square, that is, with the parts in full openposition.

Figure 2 is a view of Figure l observing the same in a direction fromright to left.

Figure 3 is a top plan View of Figure 1.

Figure 4 is a horizontal section on the line -l of Figure l.

That part constituting the so-called sheath is denoted by the numeral 5and comprises a pair of spaced parallel duplicate metal or equivalentstrips 5. At their outer or upper ends in Figure l, the parts 5 areriveted together as at l, there being a spacing washer locatedtherebetween as indicated at 8 to provide the desired parallelassemblage. Either one or both of said strips may be provided with anelongated guide and retention slot 9.

The companion or complemental part is denoted by the numeral iii andthis comprises a straight edged arm Ii having a right angularly disposedn or rib I2 extending from end to end. The outer end of said rib is outaway to provide a clearance portion as at I3 to nest against the washer8 when the structure is folded or closed. The opposite end of the rib ispivoted as at I4 between the lower ends of the side members 6 of thesheath unit 5. The stay link is denoted by the numeral I5 and is pivotedas at I5 to the intermediate portion of the rib I2. The opposite end isprovided with a stud I I slidable in the slot 9 and equipped with athumb nut I 8 and a spring lock washer I9. 'Ihe lock washer I 9 is ofthe 10 concave convex type and interposed between the thumb nut and theadjacent bearing surface of the complemental side member 6. This isbrought out to advantage in Figure 4 of the drawing. This simple lock orretention means makes it l5 possible to adjust the parts 5 and I0 intopositions at direct right angles or into various intervening anglesranging from obtuse to acute. Consequently, the device may be usedessentially as a bevel-square, or its features may be adjusted intovarying angular relationships for laying off different and varying typesof jobs. Since the device is aptly tted for use by printers, carpenters,draftsmen, and other lay-out men and mechanics, it is obvious that' therange of utility is extensive and that it is unnecessary to attempt todescribe all such activities.

It is to be observed that by pivoting the stay link I5 to one side ofthe rib I2 and slidably joining it to one of the side members 5 of thesheath, it nests itself nicely between the side members of the sheathand lies alongside of the rib I2 when the latter is folded completelyinto said sheath. Moreover, the structure is characterized by requisitecompactness and convenience, stability 35 and efliciency for precisionusage. These factors will be unquestionably clear to persons familiarwith the handling of instruments in this general category.

It is thought that the description taken in connection with the drawingwill enable-a clear understanding of the invention tov be had.Therefore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown anddescribed, it is to be understood that minor changes coming within theeld of invention claimed may be resorted to if desired.

I claim:

A foldable bevel of the class described comprising a sheath embodying apair of spaced parallel substantially duplicate side members, a spacingand assembling washer fastened between corresponding ends of saidmember, one of said 55 tion and terminating in spaced relation adjacentY the washer, an arm abutting the opposite ends of said members, saidarm being provided with a right angularly disposed flange forming a rib,the rib extending from the normal inner end of the arm lengthwise andterminating inwardly of the outer end of the arm, said terminal endbeing of curved formation to provide clearance coaction with said washerwhen the rib is folded between the members of said sheath, said innerend of the flange being pivoted between the last named ends of saidmembers, a stay link pivoted at one end to the intermediate portion ofsaid rib, ,the opposite end of said stay link being provided with athreaded stud extending through the slot, and a thumb nut on said studcooperating with said slotted member in the manner and for the purposesdescribed.
